OP – I went back to 2x because I wanted a greater gear range for my long distance rides. I’m sure someone will have posted their spreadsheet demonstrating how 1x can match 2x (but the best 1x systems cost more). I was not willing to spend the extra money on the best 1x to solve a problem i didnt really have since 2x gave me what i needed.
It’s a funny fashion 1x. Lots of people do it but often at a compromise (less slick gear changes, missing high and low gears, cassettes wearing out quickly, having to push up steep hills etc).
Also, everyone on this forum is anonymous and no one knows how each other rides, how fit, their version of a long day, trail centre, mountains or canal tow path etc. It’s only you who’ll know if it’s right for you. Try it and see how you get on. You might love it.
